Short-term rental estate appraisals in Utah — the house is real estate, the Airbnb is a business

The first thing an executor sends over on a short-term rental is almost never the deed. It's a screenshot — twelve months of gross revenue, an occupancy percentage, a 4.92 review average — sent with an obvious implication. This is what it's worth.

It isn't. Gross nightly revenue is the output of a business that happens to run inside a house. Take away the furniture, the cleaning crew, the dynamic-pricing tool, the platform listing, and four years of accumulated reviews, and the revenue goes with them. What stays behind is the part a residential appraiser is licensed to value: the land, the structure, and whatever is permanently attached to it.

So the honest frame for an inherited Utah short-term rental is that it's three assets wearing one address. Real property. Tangible personal property. And an intangible operating position made of a municipal license, a calendar, and a reputation. The date-of-death appraisal covers the first. The executor still has to account for the other two, and confusing them is how estate inventories get amended.

Three assets, one address

Split the asset before anyone talks about value, because the split decides who does the work.

• Real property. Land, improvements, built-in appliances, the hot tub if it's plumbed and wired in place. This is the residential appraisal — a retrospective, date-of-death market value on the same standard as any other one-to-four unit assignment.
• Tangible personal property. Beds, sofas, linens, kitchenware, televisions, the shed full of paddleboards. On a fully furnished resort-market unit this runs $20,000 to $60,000 and up. It is a separate USPAP discipline with separate credentials, the same credential line covered in the note on real estate versus personal property in a Utah estate.
• Intangibles. The municipal license, the booking calendar, the review history, the guest list, the listing itself. These are business assets. Valuing them is business valuation, not real property appraisal.

The reason this matters for a federal return is mechanical. Real estate is reported on Schedule A of Form 706; miscellaneous personal property lands on Schedule F. A single number covering "the Airbnb" doesn't fit either line cleanly, and the executor is the one who signs the return. The same problem shows up earlier in state court, on the § 75-3-706 inventory, which asks for each item of estate property at its date-of-death fair market value — and what Utah probate judges want to see is itemization, not a lump.

One property, two or three documents. Budget for it at the front.

Utah protects the listing, not the business

There's a widely held belief that Utah is a permissive short-term rental state. The belief traces to a real statute, and the statute does much less than people think it does.

Utah Code § 10-8-85.4 bars a municipal legislative body from enacting or enforcing an ordinance that prohibits someone from listing or offering a short-term rental on a short-term rental website — and bars using an ordinance to fine or prosecute someone solely for the act of listing. Read it carefully. It protects the advertisement. It does not create a right to operate. A city can still zone nightly rentals out of most of its residential neighborhoods, still require a license, and still enforce against actual rental activity. It just can't build its enforcement case out of the Airbnb listing by itself.

Which means permission in Utah is granted one city at a time, and the variation between cities is enormous.

Park City licenses nightly rentals through its own ordinance, and the conditions are instructive. The owner is the licensee. The unit has to sit in a zone and subzone designated as allowing rentals for the period the license covers. A valid sales tax number is required before the license takes effect. A responsible party — owner, manager, realtor, attorney — has to live within an hour's drive and respond to a complaint within twenty minutes. Every one of those conditions attaches to a person and an operating plan, not to the dirt.

Moab runs the other direction. Under Moab Municipal Code § 17.09.700, residential short-term rentals are prohibited in most zones. An estate property operating there may be legally nonconforming — grandfathered, valuable, and impossible to re-create if the entitlement lapses.

Washington County adds a second layer that catches people: even where St. George permits nightly rentals, the subdivision's recorded CC&Rs frequently don't. A property can be zoned for it, licensed for it, and still in breach of a private covenant that a neighbor is entitled to enforce.

The appraiser's job here isn't legal advice. It's establishing what the market for this particular property actually is on the effective date. A house that can legally be rented nightly and a house that can't are two different products at two different prices.

Why capitalizing the revenue produces a number nobody can defend

Here's where most inherited-Airbnb valuations go wrong.

The tempting move is arithmetic: take $90,000 of gross bookings, subtract expenses, divide by a cap rate, and announce a value. It's clean, it's fast, and it's the wrong tool for a one-to-four unit residential property. The mechanism is that a cap-rate calculation on nightly revenue values the enterprise — the furnished, staffed, listed, reviewed operating business — and then the report presents that number as if it were the real estate. It isn't. It's the real estate plus $40,000 of furniture plus an intangible operating position, wrapped in a single figure with no way to unbundle it.

The practical consequences arrive later. On an estate return, the executor has claimed a real-estate basis that includes personal property and goodwill, which is exactly the kind of overstatement that draws a second look and undermines the § 1014 step-up the family is counting on. In a contested distribution, the heir on the wrong side of the number hires their own appraiser and the enterprise-value report doesn't survive the comparison. And in a sale, the buyer's lender orders a residential appraisal that values only the real property — and the gap between the two numbers becomes the family's problem at the closing table.

There is a narrow case where an income approach earns its place: a legitimate two-to-four unit property with a stable long-term rental history, where the income approach supports the sales comparison rather than replacing it. A single-family cabin with a seasonal booking calendar is not that case.

The revenue is evidence. It is not the answer.

What the short-term rental premium actually looks like

None of the above means the premium is imaginary. It's real, it's often substantial, and it belongs in the report — it just comes from a different place than the executor expects.

Buyers in Summit, Wasatch, Grand, and Washington counties pay more for a property they can legally rent nightly. That preference is observable in the only place appraisal evidence is ever observable: what comparable buyers actually paid. So the work is comp selection, and the matching criterion is rental eligibility rather than square footage.

In practice that means:

• Verifying the subject's eligibility first — zone, subzone, license status, and any recorded covenant — because that determines which comparables are comparable at all.
• Screening comps on the same basis. Two units in the same Summit County building can sit in different rental categories. Treating them as interchangeable is the single most common error in resort-market reports.
• Extracting the premium from paired sales where the market has been kind enough to supply eligible and ineligible properties that are otherwise similar. This is real analysis and it is the part that takes the time.
• Adjusting for furnishings in the comps. Resort properties frequently sell furnished, which means the comparable's sale price contains personal property the subject's real-property value shouldn't. That adjustment has to be made explicitly, not absorbed.

Done properly, the STR premium shows up as a supported adjustment traceable to transactions. Done improperly, it shows up as a cap rate and a hope.

Paired sales beat spreadsheets. Every time.

Fee, timeline, and the retrospective wrinkle

A standard Utah residential estate appraisal runs $500 to $800, laid out in the county-by-county cost breakdown. A short-term rental prices at the upper end of that band or above it, and the premium tracks three specific things: eligibility research, a thinner and more demanding comparable set, and resort geography where drive time and price points both run higher.

Timeline follows the usual pattern in the turnaround breakdown — roughly one to two weeks from inspection to signed report — with one addition. Municipal license verification depends on a city office answering, and city offices set their own pace.

Then there's the retrospective problem, which is specific to estate work and specific to this asset class. The effective date is the date of death, which may be two or five years back. Short-term rental regulation in Utah has changed quickly over that span, and a property that is ineligible today may have been eligible then, or the reverse. The appraisal has to reflect the rules and the market as of the effective date, not as of the inspection — the same discipline described in the note on older date-of-death appraisals. An appraiser who checks today's zoning map and calls it done has answered the wrong question.

Ask for the fee in writing. An executor spends estate funds and answers for the expense.

What to have ready before the call

Fifteen minutes of gathering removes a week of back-and-forth:

• The parcel number and the exact date of death. The date fixes the retrospective effective date and the deadline the report feeds.
• The municipal license number, or the knowledge that there isn't one. This is the fact that routes the whole assignment. Include the city — resort-market properties are often described by ski area rather than by jurisdiction, and the jurisdiction is what governs.
• The HOA or subdivision CC&Rs, if the property is in a governed development. The private restriction is as binding as the public one.
• An inventory of the furnishings, even a rough one with photos. It won't go in the real property appraisal, but it's the starting point for the personal property side and for Schedule F.
• The booking history anyway. It doesn't set the value, but it does confirm the property was genuinely operating as a short-term rental on the effective date, which is a fact worth documenting.

None of it is busywork. Each item is a question that otherwise gets asked mid-assignment, when the answer costs a week.
